BUILDING-TILE.

Specification of Letters Patent.

Patented Dec. 31, 1918.

Application filed October 18, 1917. Serial No. 197,358.

To all whom it may concern:

Be it known that I, WALTER-R. Bnnnnrr, a citizen of the United States of America, residing at Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in blocks in which there will be sufficient air spaces or vacancies to prevent the passage of moisture or water and whichwill form a.

means for tying the walls securely and which will provide'the necessary strength. Other objects and advantages will be to provide blocks which can be easily mzpde or manufactured and which will not be expensive to manufacture. Reference is had to the accompanying drawings whichform a part of this application. c

Figure l is a plan view of several blocks arranged as in a wall. V of the same, showing the lowest block in section. Fig. 3 is a perspective view of one of the main wall blocks. Fig. 4 is a plan view of one of the corner blocks. Fig. 5 is a plan view of two corner blocks assembled. Fig. 6 is a perspective view of several blocks assembled as forming part of the corner wall of a building. Fig. 7 is an end view of a block, showing a variation. Fig. 8 is a plan view of a corner block, showing a variation.

Similar characters of reference are used to indicate the same parts throughout the several views.

The improved blocks are simple in construction and two or three forms of blocks Fig. Qis an elevation,

are all that are necessary in the construction of the building. The blocks 1 are of tongue and groove construction, having a groove 2 in the lower side and a tongue 3 on the tongue fitting into the groove of the block next above. 1 has a central air space spaces 5 so that no moisture or water can pass through the wall without coming into an air space or more than one air space. The

Each block 4 and lateral air blocks 1 are so arranged or placed in the wall that the wings or webs of one block are vertically in line with the blocks below and above. The pressure is thus on the strong parts of the blocks. The wings of the blocks are connected by the webs 7 and the arches 8. The corner or looking blocks 9 have grooves 10 to receive parts of tongues 3. The wings 11 of the corner blocks will be alternately arranged, that is, the wings 11 of one block will receive a tongue 3 of a block on one side and the wings 11 of the next block above or below will receive the tongue of a block on the other or adjacent side of the wall. The blocks 9 are provided with vertical openings 12 and 13 and when block 9 is placed upon another block 9, as shown in Figs. 1 and 5, no moisture can pass through any part of the corner without coming to an air space. \Vhen the moisture comes to an air space, it stops and will not go farther through the wall. The wings 11 of the corner blocks 9 will be locked between the wings or webs 6 of the blocks 1 and the corner blocks will be locked against lateral movement by the tongue? 3' and the corner blocks will lock the side and end walls against lateral movement by reason of the wings 11 engaging the tongues of the side wall blocks. Air space is left above the tongues 3, between the upper sides of the tongues and the upper walls of the grooves 2; The mortar joints 15 are shown exaggerated for clearness in illustration. Air spaces will also be left between the meeting faces of blocks. It is a well known practice with masons that mortar is placed only on the edges of tile so that there will be more or less air space between the blocks which will be entirely inclosed by the mortar and the blocks. V

The variation shown in Fig. 7 includes two ribs 16'instead of one rib or tongue, as shown in previous views, and a corresponding increase in the number of horizontal openings. Fig. 8 shows a corner block with an additional vertical opening and with an additional vertical groove to be used with such blocks as are shown in'Fig. 7.

The blocks make it possible to build walls with the greatest possible strength which are provided with ample air spaces to prevent the passage of moisture or water through the walls. The corner tie blocks provide for closing the corners without the expensive sealing heretofore practised. The

snares manna erases.

blocks are closed on the outer ends and the inner ends are prepared for interlocking with the blocks which form the Walls and at the same time the blocks eliminate the trou- 5 ble of moisture penetrating the walls' lVhatl claim, is,

1. A Wall composed of horizontally disposed blocks having longitudinal grooves in their lower sides and longitudinal tongues on their upper sides for interlocking with each other and having pluralities of longitudinal openings therethrough, and corner tie blocks substantially U-shaped, being closed /at one end and having vertical grooves in 1 5 the other ends, sald tie blocks belng altersubstantially U-shaped, being closed at one.

end and having vertical grooves in the other ends and alternately arranged to receive portions of the tongues of alter-nate layers of said horizontally disposed blocks and having pluralities of vertical openings communicating with openings of alternate blocks and communicating With the open ings in said horizontal blocks for intercepting all mortar joints for preventing moisture from passing through the Walls.

3. A Wall composed of horizontally disposed hollow blocks having interlocking horizontal tongues and grooves and substantially U-shaped corner tie blocks closed on their outer ends and having relatively long vertical grooves in their inner ends and said corner blocks being alternately arranged for receiving in their grooves portions of the tongues of alternate layers of said horizontally disposed blocks, said corner blocks having communicating vertical openings for forming air spaces to prevent the passage of moisture through the Wall.

In testimony whereof, I set my hand, this 10th day of October, 1917.

WALTER R. BENNETT.
